Fix Unicode support and improve navigation functionality

- Fix album cover path generation for Unicode artist names (Beyoncé, Björk, etc.)
- Improve Next button to respect current filter/sort state instead of just incrementing rank
- Add proper Unicode character handling with regex property escapes
- Update README to document new Unicode support and smart navigation features
